What we see
Plate and frame heat exchangers are precision systems that can lose significant heat transfer efficiency when fouling builds up unchecked. While ultrasonic cleaning is a common first step, it is not always sufficient. Heavy scaling, biological fouling, oil and grease accumulations, and complex geometries can prevent ultrasonics from fully dislodging deposits. In some cases, contamination resides within narrow channels or permanently welded plates, making removal even more challenging with standard cleaning techniques.
When contaminants such as mineral scale, oils, or biological residues are not completely removed, they reduce heat exchanger efficiency, shorten the time between cleanings, and risk permanent damage to the plates. Over time, residual contamination can carbonize — rendering the heat exchanger irreparable and requiring costly replacement.
Carolina PEC's heat exchanger cleaning company technicians assess contamination type and severity before recommending a cleaning approach, so you're never paying for a process that won't work.
What we do
At Carolina Process Equipment Cleaning (Carolina PEC), we go beyond ultrasonic cleaning to restore the performance and longevity of plate and frame heat exchangers. Every engagement begins with a contamination assessment — we identify the deposit type and select the most effective method before work begins. Our approach includes:
-
Specialized Cleaning Techniques: Advanced chemical cleaning agents, mechanical methods, and high temperature processes to break down and remove stubborn deposits including mineral scaling, oils, and biological fouling.
- Targeted Chemistries: Specialized cleaning solutions to address contaminants such as grease, oil, algae, and bacteria, ensuring complete removal.
- Advanced Inspections: Thorough inspections to verify all contamination has been successfully removed from channels, tight spaces, and welded plates before reassembly.
Our proven cleaning methods ensure heat exchangers return to service fully restored, maximizing efficiency, reducing downtime, and extending the on-stream life of these critical systems.
We serve process plants across a range of industries including petrochemical and refining, specialty chemicals, pharmaceutical, power generation, and food and beverage.
